To all whom, mttypcoiwern.:

Be it known that I, MERTON Ross SKINNER, a citizen of theUnited'States,residing at Levrroy, in the county of Genesee and State of New York,have invented a new and yuseful Window-Screen, of which the following isa "specication This inventionlrelates to window-screens, and has for.its object to' arrange for mounting the screens upon the top and bottomof a wintomatically connecting-the. sash to there-J spective screens bymovingthe sashes to their closed limits, whereby either screenmay Abebrought into operative position by closing` either sash and thenopeningthe same to any desired extent.

A further object is to normally maintain the free edges of the screensin position to be readily engaged by thesashes without obstructing theopening in 'the window-frame. Another object is to provide an improvedspring-mounting of the screen, so as to facili-v tate the placing ofthe'spring-roller within the window-frame and also to automatically windup the screen when the 'latter has been de' tached from the sash. Y l

A final object is to providefor interlocking the two saslies,` so as toovercome the combined action of the sash-weights and the spring-roller,and-thereby to hold either sash in an open position. v u

With these and other objects in view the present invention consistsinthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings,and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claims without departing from the spirit or sacrificing anyof the'ad-l l vantages of the invention.

In the drawings,Figure 1 is an elevation of the inner side of awindow-frame having the present inventiona'pplied thereto, parts beingbroken away to'illustrate the mounting of the screens. sectionalviewvillustrating'the connection of the upper freee'dg'e of the lowerscreen with thelower end vofthe lower sash. Fig. 3 is a detail sectionalviewof one of the latches car# ried by the, window-sash. Fig. 4 is adetail View showing'the manner of connecting one of the catches to theupper screen.

Fig. 13 is an yenlargeddetail cross-'sectional view taken on the line/y y of Fig! 9. `Figllf isa detail perspective iviewlof the fastening for interlocking the twosashes.

Like characters of referencedesignate corresponding parts in all thefigures of lthe draw Referring at first more particularly to Figs. 1 to8, inclusive, of the accompanying draw- Fig. 2 is an enlarged detailings, 1 designates' an ordinary windw`frame,

having the usual upper and lower sashes 2 and 3, respectively, theseparts being common and well known and shown in the drawings merelyto'more adequately illustrate the application and operation of thepresent invention. 1

It will be understood that it is designed to provide a screen-closurefor the openings between the window-sill and the lower` sash and theupper end of thefraine andthe upper sash whenthe sashes are'open, andtoaccomplish this purpose there are provided the upperand lower screens 4and 5, respectively, of which the upper screen is carried byaspringroller 6, mounted within the wall of the buildd4 f ing and abovethe top of the window-frame,{

IOC

while the lower screen 5 is adapted to slide vertically in a suitablespace provided in the wall and having its lower edge provided with aweight-strip 7 to insure a proper movement of the screen. While it ispreferable to mount the lower screen so as to slide vertically, it mayalso be carried by a spring-roller mounted within or below thewindow-sill,such construction being shown in Fig. 9 of the drawings.

As plainly illustrated in Fig. S, it will be seen that the window-sill 8is provided with alongitudinal slot 9, through which the screen isadapted to Work, and it will of course be understood that the upper endof the window-frame is also provided with a similar slot for thereception of the upper screen, as indicated at 10 in Fig. 1 ofthedrawings. The connection between the screens and the respective sashesbeing the same in each case, a description of one of these fastenings isdeemed suiiicient. As best illustrated in Fig. 2, it will be seen thatthe upper free edge of the screen 5 is provided with a metallicstiffening and strengthening strip 11, which is designed to t within agroove or seat 12 formed in the lower edge of the bottom of the lowersash. At each upper corner of the screen there is provided a catch 13,which is formed from a liat strip of metal that is twisted intermediateof its ends, so that the latter may lie in planes at substantially rightangles to each other, the lower end being applied flat against theadjacent strip 11 and secured thereto by means of a suitable fastening14, the opposite upper end of the strip being provided with a catchprojection 15, which is directed laterally inward. The lower portion ofthe outer edge of the adjacent sash 3 is provided with a vertical recess16 for the reception of the catch, and the latter is connected to thesash by means oi a latch 17, consisting of a casing which is projectedthrough the inner edge of the sash and has an endwise-movable bolt 18,that extends into the recess 1G'and bengages with the catch-head 15.Within the casing and hearing in opposite directions against the latterand the bolt there is a helical springlf) to normally force the beveledend of the bolt outwardly into the recess, the opposite end of the boltbeing provided with a knob or fingerpiece 20, which is projected attheinner edge of `the adjacent side rail of the sash, so as to be inposition for convenient manipulation to disengage the bolt from thecatch.

As clearly indicated in Fig. 3, it will be seen that the bolt isprovided with a lateral pin or projection 21, which works in alongitudinal slot 22, formed in the casing, so as to form a guide toprevent accidental rotation of the bolt, and a transverse notch 23 isformed in the casing and communicates with the inner end of the slot 22,so that when the bolt has been retracted it may be rotated to turn theprojection 21 into the notch 23, and thereby lock the bolt in itsretracted position, so that it may not engage with the adjacent catch ofthe screen. It will of course be un derstood that each side ot' thescreen is provided with a catch, and each side of the sash is providedwith a spring-actuated latch-bolt, so that the screen may be effectuallyconnected to the sash. By reason of the fact that the bolts and catchesare beveled the same will be automatically engaged when the sash hasbeen pushed down to its lowermost limit, whereby it is not necessary tomanipulate the fastenings to engage the screen with the sash.

Upon reference to Fig. S of the drawings it will be seen that thewindow-sill is provided with an upstanding strip 24, located at theouter side ofthe slot 9, so as to form aweatherstrip for the'latter andalso designed to enter the groove or recess in the bottom of the sashwhen the latter is closed, so as to form a tight joint between the sashand the windowsill for the exclusion of dampness, the.

To prevent the lower screen from passing entirely through the slot inthe sill when the screen and sash are disconnected, the lower end ofeach catch 13 is provided with a lateral outwardly-directed anddownwardly-im clined foot 25 to rest upon the similarly-inclined sill,and a stop projection 2G is provided upon the opposite side of the catchand is formed by a head on the fastening 111,y

whereby this foot and the projection form stops to limit the downwardmovement ofthe screen, and thereby prevent the latter from passingdownwardly through the slot. The catch shown in Fig. 7 is designed forthe upper screen and is provided with a screwthreaded fastening 27, thatis 'countersunk in the upper end of the catch and designed for`connection with the metallic strip of the upper screen, so as to avoidprojections. At a suitable distance inwardly from each upper catch ascrew or bolt 29 pierces the metallic strip 30 and is provided with anut 34E, located upon the opposite side of the strip and IOO IIO

designed to form a stop for engagement with the upper end of thewindow-frame to prevent the screen from passing through the slottherein. Each catch may be braced by means of an ear or portion 31 cutfrom the adjacent stii'fening-strip and bent outwardly against thecatch, as indicated in Fig. 4.

It will be understood that the catches of the upper screen travel infront of the parting strip or bead carried by the window-frame, and inorder that access may be had to these catches the upper portion of saidstrip or bead is made separate from the remaining portion, as indicatedat 32 in Fig. 1 and also indicated by dotted lines in Fig. 5, saidseparate portion being held in place by means of the fastening 33,whereby this section may be re moved to give access to the catch forapplying and removing the same.

For an understanding ol" the mounting of the spring-roller reference ishad to Figs. 10, 11, and 12, inclusive, wherein it will be seen thateach end of the roller is provided with a journal 35,which is passedinwardly through an opening 36 in the adjacent side piece 37 ofthewindow-frame and into a longitudinal opening 38, formed inthe endofthe roller, the outer end of the journal being projected a suitabledistance at the outer vside of the window-frame and provided with alongitudinalslit or bifurcation 39.

roller and the journal 35 and has its opposite ends bent or upsetvagainst the opposite sides of the roller, thereby connecting thejournal to the roller to prevent independent movements thereof.. Acoiled spring 42 has its inner end portion 43`iitted in the slit orbifurcation in the outer'end ofthe journal andits opposite outer endconnected to the adjacent frame portion 37 by means of a bolt or othersuitable fastening 44. A plate 45 is applied to the outer end ofthejournal, sov

as to cover the outer edges of the spring-coils,

and a suitable split key 46 is passed through a transverse opening inthe outer end of the journal, so as to hold the plate in place. By thismeans each spring-roller maybe conveniently mounted in placewithoutrequiring any particularly-adapted roller-brackets.

In view of the combined tension of each spring-roller and thesash-weights itis ap# parent that it is necessary to lock the sashes tohold them'in their open positions, and toV accomplish this result therehas been pro` vided a locking-bolt 47, which is mounted to slide in anendwise direction throughthe up-4 1 per end of the lower sash andadapted to en,- gage the upper sash, so as'to interlock the two sashes,and thereby offset the actionof the two springrollers,fand thus holdVthe sashes stationary in any open position. The

locking-bolt is provide'dwith an enlarged in.`

ner end portion 48, which is beveled upon one side, as indicated at 49,said beveled end being adapted to coperate with a plurality of keepers50, carried by the adjacent side piece of the upper sash, and-preferablyin the form of staples driven into the `sash.` lThe' bolt is mountedwithin a suitable vtubular casing 51, which is snugly fitted in anopening formed through the lower sash, lthe inner end of said openingbeing enlarged, as at 52, for

the reception of the outwardly-directed marginal flange 53 at the innerend of the casing.

A helical yspring 54'fencircles the bolt andA bears in oppositedirections against the outer end of the casing and the enlarged innerend of thebolt, thereby to normally hold the lat# ter projected intoengagement with the upper sash. The bolt is also rotatably adjustable,so

as to change the position of its beveled inner end, and for this purposeit is provided at its outer end with across-head" or cross-bar 55, tothe opposite ends of which are Yconnected suitable operating-cords 56,which depend from the bolt and are designedfor convenience in rotatingthebolt by pulling downwardly upon either cord. The projected inner endof the bolt is provided with a lateral i stud or projection 57,v and theinner end of A wire pin orV key 40 is driven transversely through thethecasing is provided withlongitudinally-dis posed stop projections 58and 59, which are located in the path of the'movement of the stud orprojection 5.7 so as to form stops to limit the rotatable movement ofthe bolt'to a semirotation, the casing being provided with slots 60 and6l, located next Vto the respectiveI stop projections,'so as to receivethe stud 57 when the bolt is withdrawn out of engagement 'with thekeepers of theupper sash. In the `position shown in Fig. 13 thelocking-bolt is disposed withits beveled face49 upwardly,

whereby the sashes are interlocked, so as to prevent independent upwardmovementof the upper sash and downward movement of the lower sash.Should itbevdesired to close' either sash, the bolt is rotated so as tobring the beveled face thereof into engagement with the adjacent keeper,whereby thesashes may then be moved invopposite directions, as thebeveled end of the` -bolt"will work over lthe v keepers. f

What I claim is- I able with the sash, opposite catches carried.
